Iibhetri zeLithium zezona teknoloji zebhetri zihamba phambili namhlanje, ezinoxinano lwamandla aphezulu, ubomi obude, ukuzikhupha okuphantsi, ukukhuselwa kwendalo kunye nezinye izibonelelo.Zisetyenziswa kakhulu kwii-smart phones, iilaptops kunye nezinye iimveliso zombane, kunye nezithuthi zamandla amatsha kunye namandla omoya, amandla elanga kunye nezinye izixhobo zokugcina amandla amakhulu.Ngeenjongo zokuncitshiswa kwekhabhoni yehlabathi, ukuguqulwa kombane kunye nemigaqo yomgaqo-nkqubo, imfuno yemakethe yebhetri ye-lithium ibonisa ukukhula okuqhumayo.Kulindeleke ukuba ngo-2025, ubungakanani bemarike yebhetri ye-lithium yehlabathi buya kufikelela kwi-1.1 yeetriliyoni zeedola zaseMelika.
Ukusebenza kunye nomgangatho weebhetri ze-lithium azixhomekanga kuphela kumsebenzi kunye nokuzinza kwee-ion ze-lithium, kodwa kunye nokukhethwa kunye nomlinganiselo wezinto zebhetri.Phakathi kwabo, i-magnesium carbonate yinto ebalulekileyo yebhetri, esetyenziswa kakhulu ukwenza i-precursor yezinto ezilungileyo ze-electrode, kwaye ingasetyenziselwa ukuphucula ubume kunye nokuhamba kwezinto ezimbi ze-electrode.I-Magnesium carbonate idlala indima ebalulekileyo kwiibhetri ze-lithium, kodwa ungakhetha njani umgangatho ophezulu we-magnesium carbonate?Nanga amanye amacebiso:
- Khangela ukuba umxholo oyintloko we-magnesium carbonate uzinzile.Umxholo oyintloko we-magnesium carbonate ubhekisela kumxholo we-magnesium ion, elawulwa ngokubanzi phakathi kwe-40-42%.Umxholo we-ion we-magnesium ophezulu kakhulu okanye ophantsi kakhulu uya kuchaphazela umlinganiselo kunye nokusebenza kwezinto ezilungileyo ze-electrode.Ngoko ke, xa ukhetha i-magnesium carbonate, khetha abo bavelisi ngeteknoloji ephezulu yokuvelisa kunye nenqanaba lobuchwepheshe.Bangakwazi ukulawula ngokuchanekileyo umxholo we-magnesium ion we-magnesium carbonate kwaye baqinisekise umgangatho wokomisa kwemveliso kunye nokususwa kokungcola.
- Jonga ukuba ingaba ubumdaka obuzibuthe be-magnesium carbonate bulawulwa kuluhlu oluphantsi.Ukungcola kwamagnetic kubhekisela kwizinto zetsimbi okanye iikhompawundi ezifana nentsimbi, i-cobalt, i-nickel, njl., Okuya kuchaphazela isantya sokufuduka kunye nokusebenza kakuhle kwee-ion ze-lithium phakathi kwe-electrode efanelekileyo kunye ne-negative, ukunciphisa umthamo kunye nobomi beebhetri.Ke ngoko, xa ukhetha i-magnesium carbonate, khetha ezo mveliso ezinobumdaka obuzibuthe obungaphantsi kwe-500 ppm (enye kwisigidi), kwaye uziqinisekise ngezixhobo zovavanyo lobuchwephesha.
- Jonga ukuba ubungakanani bamasuntswana e-magnesium carbonate buphakathi.Ubungakanani besuntswana le-magnesium carbonate buya kuchaphazela i-morphology kunye ne-crystallinity yezinto ezilungileyo ze-electrode, kwaye emva koko zichaphazela ukusebenza kwentlawulo-ukukhutshwa kunye nokuzinza komjikelo weebhetri.Ke ngoko, xa ukhetha i-magnesium carbonate, khetha ezo mveliso ezinobungakanani bamasuntswana amancinci kunye nobukhulu obufanayo kunye nezinye izinto.Ngokuqhelekileyo, ubukhulu be-particle D50 (okt, i-50% i-cumulative distribution particle size) ye-magnesium carbonate imalunga ne-2 microns, i-D90 (oko kukuthi, i-90% i-cumulative distribution particle size) imalunga ne-20 microns.
Ngamafutshane, kumxholo wokwandiswa ngokukhawuleza kwemakethe yebhetri ye-lithium, i-magnesium carbonate njengento ebalulekileyo yebhetri, umgangatho wayo uchaphazela ngokuthe ngqo ukusebenza kunye nomgangatho weebhetri ze-lithium.Ngoko ke, xa sikhetha i-magnesium carbonate, kufuneka sikhethe ezo mveliso ezinomxholo oyintloko ozinzile, ukungcola okuncinci kwamagnetic kunye nobukhulu be-particle ukuze kuqinisekiswe ukusebenza kakuhle kunye nokusetyenziswa kwexesha elide leebhetri ze-lithium.
